chore(release): 0.0.7

Squash-merge lib-standardisation: adopt repo standards across packaging,
tooling, docs, and CI.

- standardize pyproject.toml (canonical packaging, lint config, extras, GSDFC pydoclint)
- add py.typed marker, modernize type hints and Google-style docstrings
- nest generated docs under docs/lib and docs/mcp; add hand-written wiki
- adopt standard Type A PyPI CI pipeline (tag==version guard + quality gate)
- promote generated CHANGELOG.md; bump version to 0.0.7

+# Library Overview
+
+`docforge` turns GSDFC-compliant Python docstrings into maintainable reference
+documentation. It never edits source docstrings; it reads them, renders them,
+and assembles documentation sites from all available material.

+## 🧭 Which Build Should You Use?
+
+| Kind      | Source                     | Output                          |
+|-----------|----------------------------|---------------------------------|
+| `lib`     | GSDFC docstrings           | `docs/lib/**` rendered markdown |
+| `api`     | OpenAPI JSON spec          | `docs/api/**` rendered markdown |
+| `wiki`    | Hand-written markdown      | `docs/wiki/**` (unchanged)      |
+| `mcp`     | GSDFC docstrings + renderers | `docs/mcp/**` structured JSON |
+
+---
+
+## 🏗️ Architecture
+
+Each enabled site kind produces its own MkDocs configuration and build:
+
+1. `--mkdocs` (lib) writes `docs/mkdocs.lib.yml` and builds `site/lib/`.
+2. `--api` writes `docs/mkdocs.api.yml` and builds `site/api/`.
+3. `--wiki` writes `docs/mkdocs.wiki.yml` and builds `site/wiki/`.
+
+Every site is self-contained (own theme assets and search index) with
+navigation derived or scoped to that kind. Hand-written wiki content is never
+overwritten or regenerated — only its navigation is derived automatically.
+
+---
+
+## 🔄 Lifecycle Rules
+
+`docs/mcp/**` is a self-contained, machine-readable reference generated from
+docforge's own GSDFC docstrings. `doc-forge serve --mcp --module docforge`
+serves it over MCP. See the [MCP Guide](05_development/04_mcp_guide.md).
